Medical Dopplers have been extremely beneficial in the field of medical diagnosis of various diseases. Not only has Doppler sonography made it possible to diagnose a wide range of physiological conditions using a non-invasive and painless procedure, but the ultrasound has also saved millions of would-be mothers during pregnancy. The field of gynecology has benefited the most from Doppler sonography, and many women and children owe their lives to this wonder machine!How Does the Doppler Work?A basic ultrasound Doppler device uses the technology of SONAR (Sound Navigation and Ranging) along with the Doppler shift methodologies to get an accurate picture of soft tissues within the body. An ultrasonic sound wave is produced by a transducer within the device, and this high-frequency wave travels through the tissues of the body and gets reflected from the desired portion that requires to be analyzed. This echo technology has made it possible to obtain clearer images using the Doppler device.There are three main types of Doppler tests that are currently in use for diagnostic purposes in hospitals. These are the pulsed Doppler ultrasound test, the color Doppler ultrasound test and the power Medical dopplers ultrasound test. The pulsed Doppler and color Doppler tests are more popular and are widely applied for various cardiac and gynecological diagnostic tests.Importance of UltrasonographyThe importance of a Doppler test cannot be emphasized enough. Some of the most important applications of a Doppler ultrasound are:• During pregnancy: The ultrasound test is one of the first major tests that women usually go for after a pregnancy has been confirmed. The ultrasound not only detects the fetus inside the womb of the mother, but it also helps in monitoring the blood flow of the baby. Ultrasounds become a regular affair during a pregnancy and are very useful in detecting any abnormal activities that may be harmful to the mother or the child.• Detecting cardiac blockages: The ultrasound also helps in the detection of heart blockages in cardiac patients. Early detection of narrowed vessels and coronary blockages help in the prevention of major strokes and is a life-saving procedure.• Prevention of brain strokes: Ultrasound tests also help in detecting blockages in the carotid artery which carries blood to the brain. The accurate and timely diagnosis of a carotid blockage helps in the prevention of brain strokes in patients.• Transcranial ultrasound: This kind of ultrasound test use a Doppler device to detect and monitor blood flow through the brain after the patient has suffered a brain stroke.Thus, buying a high-quality Doppler device is extremely useful in hospitals and diagnostic clinics. What matters most in the medical field is the timely diagnosis of any major disease or abnormality in the functioning of the internal organs of a patient. With a good quality ultrasound, many lives can be saved, and doctors can treat patients much more successfully.
